Abundancia y fluctuaciones de aves limícolas (Charadriiformes) en una playa fangosa de Chomes, Costa Rica
Barrantes Montero, Gilbert; Pereira Pérez, Ana Isabel (1992)We recorded 27 species of Charadriiformes on the mud flats of Chomes, Golfo de Nicoya, Costa Rica, during biweekly censuses over one year. These were grouped taking into account their abundance and permanence on the flat. ... -
Alimentacion de pichones, exito reproductivo y notas sobre cuido parental en yiguirros (Turdus grayi): el rol de las hembras y machos
Sánchez Ulate, Natalie Viviana; Vargas Castro, Luis Esteban; Barrantes Montero, Gilbert (2018)Las hembras frecuentemente invierten ma ́s que los machos en cuido parental, pero en sistemas sociales monogamos, los machos invierten tanto como las hembras en el cuido de su progenie y se estima que esta contribucion ... -
Artificial cavities and substrates for cavity-nesting birds in Neotropical urban environments: A novel resource or the last opportunity to breed?
Sandoval Vargas, Luis Andrés; Rojas Valerio, Emmanuel; Retana López, Marco; Gutiérrez Vargas, José Ignacio; Barrantes Montero, Gilbert (2021)Urban development reduces the abundance of most natural resources for some birds but also provides new opportunities for others. One group that is more likely affected by urban development is the cavity-nesting species ... -
Asociación entre la morfología alar y el uso del hábitat en seis especies de palomas (Columbidae) neotropicales
Ocampo Vargas, Diego; Alvarado Barrantes, Angélica; Álvarez, María José; Ríos Acuña, Adrián; Barrantes Montero, Gilbert; Sandoval Vargas, Luis Andrés (2019)Biomechanics, behavior, and natural history influence wing dimension and shape. Wing design often correlates with features of the habitat in which each species is found. Doves and pigeons (Columbidae family) range from ... -
Birds in Coastal and Marine Environments
Barrantes Montero, Gilbert; Chaves Campos, J. (Springer Science & Business Media, 2009)In Costa Rican coastal and marine environments (e.g., estuaries, mud- flats, islands, open ocean) 96 bird species have been recorded, 11% of the total avifauna in the country. This high diversity is primarily explained by ... -
Blooming plant species diversity patterns in two adjacent Costa Rican highland ecosystems
Cristóbal Pérez, Edson Jacob; Barrantes Montero, Gilbert; Cascante Marín, Alfredo; Madrigal Brenes, Ruth; Hanson Snortun, Paul; Fuchs Castillo, Eric J. (2023-01-12)The Costa Rican Paramo is a unique ecosystem with high levels of endemism that is geographically isolated from the Andean Paramos. Paramo ecosystems occur above Montane Forests, below the permanent snow level, and their ... -
Canines as a measuring tool for leaf tent construction in Dermanura watsoni
Villalobos Chaves, David; Barrantes Montero, Gilbert; Fuchs Castillo, Eric J.; Rodríguez Herrera, Bernal (2013)Many animals are capable of constructing structures to modify the environment for their own benefit. The design of these structures requires animals to perceive dimensions. However, how animals take measurements to achieve ... -
Carrion Feeding By Spiderlings Of The Cob-Web Spider Theridion evexum(Araneae, Theridiidae)
Barrantes Montero, Gilbert; Weng, Ju Lin (2007)The use of carrion to feed spiderlings has never previously been observed in spiders. Here we show that the theridiid Theridion evexum Keyserling 1884 stored dead insectan prey for up to one week prior to the emergence of ... -
Characteristics of male Spot-bellied Bobwhite (Colinus leucopogon) song during territory establishment
Sandoval Vargas, Luis Andrés; Barrantes Montero, Gilbert (2012)In song-learning birds, male song shows a large inter-individual variation that frequently plays an important role in intra- and inter-sexual selection. In other bird groups, such as Galliformes, song learning is absent, ... -
Characteristics of the capture threads of Synotaxus sp. (probably S. turbinatus) webs (Araneae, Synotaxidae)
Barrantes Montero, Gilbert; Triana Cambronero, Emilia (2009)Synotaxus spiders have independently evolved aerial, planar webs to intercept and retain prey, but these webs differ in several respects from planar araneoid webs with similar functions. The silk capture threads of Synotaxus ... -
Characteristics of the cocoon and natural history of the gregarious Meteorus restionis sp. n. (Hymenoptera, Braconidae, Meteorinae) from Costa Rica
Barrantes Montero, Gilbert; Triana Cambronero, Emilia; Shaw, Scott; Jones, Guinevere (2011)A new species of a gregarious Meteorus wasp (Braconidae) constructs an unusual cocoon mass. Meteorus restionis sp. n. is described and distinguished from similar species. Cocoons of M. restionis are dark-brown, ovoid, and ... -
Cocoon web induced by Eruga telljohanni (Ichneumonidae: Pimplinae) in Leucauge sp. (Tetragnathidae)
Barrantes Montero, Gilbert; Sandoval Vargas, Luis Andrés; Hanson Snortun, Paul (2017)The hosts and cocoon webs of koinobiont-ectoparasitic wasps in the genus Eruga Townes in Townes & Townes, 1960 are known for only two species. We describe here the host spider and cocoon web of a third Eruga species: E. ... -
Comparación del peso de diferentes tipos de plumas entre cinco especies de aves del páramo de Chirripó, Costa Rica
Barrantes Montero, Gilbert (1993)Plumage weight was compared in highland and wide-range bird species (N= 18 weight samples): Sooty Robín (Tutdus nigresce/lS). Rufous-collared Sparrow (Zonotrichia cape/lSís), Volcano Junco (íunco vulcani), Slaty Flowerpiercer ... -
Complex behavioral plasticity is not lost in spiderlings with miniature brains
Quesada Hidalgo, Rosannette; Eberhard Chabtree, William G.; Barrantes Montero, Gilbert (2021-06-16)The brains of smaller animals are smaller than those of their larger relatives, but it is not clear whether their adaptive behavioral flexibility is more limited. Previous interspecific comparisons found that aspects of ... -
Conceptual and statistical problems with the use of the Shannon-Weiner entropy index in bioacoustic analyses
Sandoval Vargas, Luis Andrés; Barrantes Montero, Gilbert; Wilson, David R. (2018-04-03)Information theory and its indices were developed for human communication to predict the amount of information transferred in a message. One such index, the Shannon-Weiner index (SWI), has often been used to analyse ... -
Conspecific and predator perception of the Red Oophaga pumilio Morph from the Central Caribbean of Costa Rica
Chaves Acuña, Wagner; Sandoval Vargas, Luis Andrés; Bitton, Pierre Paul; Barrantes Montero, Gilbert; García Rodríguez, Adrián (2020-11-04)Strawberry Poison Frogs (Oophaga pumilio) are common members of leaf litter lowland communities in Central America and exhibit several color morphs throughout their distribution. Color plays a determinant role during intra- ... -
Construction and function of the web of Tidarren sisyphoides (Araneae: Theridiidae)
Madrigal Brenes, Ruth; Barrantes Montero, Gilbert (2009)In this paper, we describe the construction and function of the double sheet and tangle web of Tidarren sisyphoides (Walckenaer 1842). Web construction includes several stages: construction of the scaffolding that serves ... -
Courtship behavior and copulation in Tengella radiata (Araneae, Tengellidae)
Barrantes Montero, Gilbert (2008)The first description of the courtship behavior and copulation is provided for Tengella radiata (Kulczynski 1909). The male courts the female by rocking his body and vibrating his abdomen. These behaviors seem to induce ... -
Courtship, egg sac construction, and maternal care in Kukulcania hibernalis, with information on the courtship of Misionella mendensis (Araneae, Filistatidae)
Barrantes Montero, Gilbert; Ramírez, Martín J. (2013)Morphological and behavioural traits place Filistatidae basally within Araneomorphae, although some features, such as their continuing to moult after reaching adulthood, are reminiscent of mygalomorph spiders. This paper ... -
Cues guiding uloborid construction behavior support orb web monophyly
Eberhard Chabtree, William G.; Barrantes Montero, Gilbert (2015)Behavior can provide useful traits for testing phylogenetic hypotheses, and some details of orb web construction behavior have been especially useful in characterizing higher-level groups in spiders. The cues used to guide ...
